We have known Traco to use spiral balances, like our Series 600, in their windows. There's a chance you may just need to adjust them with a charging tool, like our 75-006. We included some helpful media guides on this page that shows how to charge the balance. In regards to different lengths in the same window, the top and bottom sash are different. Usually the top sash balance is 2" less than the bottom sash. |
